Alternative and improved syntheses of highly potent and selective A 3 adenosine receptor agonists, CI-IB-MECA and thio-CI-IB-MECA

Abstract

Improved syntheses of potent and selective A3 adenosine receptor agonists, CI-IB-MECA and thio-CI-IB-MECA were accomplished from cheap stating material, D-ribose. New synthetic methods were found to be superior to old methods from the viewpoint of use of cheap starting material, number of steps, and overall yields.
